KUALA LUMPUR, Malaysia (AP) — Malaysia says searches have begun in both the northern and southern corridors of a vast swath of Asia where the missing Malaysia Airlines jet is believed to have ended up.

Malaysian Defense Minister Hishammuddin Hussein says that Kazakhstan joined the search Monday in the farthest northwest section of the search area. Earlier Monday, Australia said was taking the lead in searching over the southern Indian Ocean.

Malaysia Airlines Flight 370 with 239 people aboard went missing March 8 en route to Beijing. Investigators say it was deliberately diverted.

Malaysian authorities say satellite data shows the plane sent a signal about 7 ½ hours after takeoff — shortly before it would have run out of fuel — from somewhere on a huge arc stretching from Kazakhstan to the southern Indian Ocean.
